Overview

CVE-2024-47750 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08

Currently rsv_qp is freed before ib_unregister_device() is called

on HIP08. During the time interval, users can still dereg MR and

rsv_qp will be used in this process, leading to a UAF. Move the

release of rsv_qp after calling ib_unregister_device() to fix it.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
